Enhance Ride-Through Capability of Adjustable Speed Drives by Maintaining DC-Link voltage

S.S.Deswal, Ratna Dahiya and D.K.Jain

Abstract—Electric power quality encompasses voltage transients, sags, swells, voltage distortions and momentary interruptions (outages) etc There are different techniques to enhance ride-through capability of ASD’s during voltage sag conditions. These are aimed at maintaining the DC-link voltage constant by injecting energy from an external source. Ultracapacitors, as storage device, are of reduced size as compared to batteries and provide fast energy exchange. In this paper, the improved performance of ASD’s with Ultracapacitors at DC- link during various electric power system faults is demonstrated using MATLAB simulation.and physical experiments were carried out to verify the correctness and validity of proposed ASD ride through topology and control strategies.The performance of ASD under healty and abnormal condition is first simulated in MATLab simulink and then the same are verified using designed hardware setup. The LABView (8.5) software and DAQ board has been used to record the generated waveforms during various power quality disturbances.

Index Terms—Ride-through topologies, Power Quality, Adjustable speed drives, Ultracapacitors, ultracapacitors.
